Laser head and paper rolers need cleaning geting speckles. Have drum out but how do i get it them and what is best to clean them with
Spots on the laser glass would show up as white vertical stripes in your print.
The drum unit has a soft plastic blade inside it to constantly clean the drum as it turns. Sometimes a clump of toner gets caught under the blade, but that usually shows up as a narrow band of spotty or gray stuff down the page. The clump may carve a groove in the drum, too. The cure is to replace the drum unit, unless it's new, in which case the cure is to make the store replace the drum unit.
In the back of the printer is the fuser, which runs the paper between hot rollers to bake the powder into the paper. The rollers are coated with Teflon or similar stuff, to prevent picking up toner and laying it back down further down the page. With age & use, the coating fails, and spots appear. Look for a pattern that repeats every 3 inches or so as the roller comes around.
Brothers are also prone to spot due to a bad toner cartridge. Take the toner cartridge out of the drum cartridge, hold it over a sheet of paper or two, and try to shake toner out of it. A little toner spill is normal, but if you get a pile under one end, a seal has gone bad in the cartridge. You need a new toner ctg.
Every manufacturer wants you to spend your money on their own supplies, of course, but in the case of Brother laser printers & faxes, refilled toner cartridges can sometimes break your machine. At the end of the cartridge is a wheel that stirs the toner inside; it's engaged by a thing in the machine that comes out as you close the toner door. Brother uses toner with smooth, round particles in their cartridges. Some refillers use toner that's just as fine, but ground to rough shapes. It resists stirring enough to sometimes break the gear inside the machine, making for an expensive repair. That's not your problem here, but you should consider that if you're headed to the store for new toner.
